这是一篇pymupdf实例，操作方法是pymupdf的作者jorj.x.mckie 提供的。
实例是这样的：别跟我说乱码问题，如果有是自己程序有问题，给我留言我给你回复：[email protected]
比如我要把pdf中某些区域原样（有各种图文）拷贝。
First you can use for keywords on a page via page.searchFor(“text”, …). This will give you a list of rectangles where the text can be found. Using this for several different keywords allows you to calculate a rectangle “rect” that you want to be displayed in a new document page.
首先找到关键词，定位需要拷贝的内容：也就是rect的定点参数，左上角，和右下角。
然后用showpage将内容拷贝到新的pdf文档中即可。
说实话大牛的职业态度确实赞。
Then, on “newpage” in you new document “newdoc”, do this: newpage.showPDFpage(newrect, doc, pno, clip= rect, …),
Where:
- newrect is the rectangle of the new page where the stuff should appear
- doc is the old document
- pno is the page number of the old document*s page
- rect is your calculated area to show
